The Babylonian Talmud is a must for every Jewish home. Christians will find it very useful as well. You will probably never read every volume, but it is a great reference library to the Old Testament. And the price can't be beat.
This is not a bad buy for someone starting to study Talmud.If a christian wants to go toe to toe in rabbinic debate or understand early church and rabbinics this will help, however you might also want to invest in Koren's (Steinsaltz) or Artscroll's Sha (Talmud). Even though Neusner's is good for the beginner, I pray christian books makes a deal with Artscroll or Koren. The commentary to the talmud text is critically worth it to understand to connect between christian and (Orthodox) rabbinic thought.
